Maintaining fiber alignment in extrusion processes is crucial for enhancing mechanical properties. Research suggests that both high and low screw speeds play significant roles in fiber alignment. High-speed extrusion can lead to challenges in throughput stability and melt homogeneity, affecting fiber alignment. On the other hand, low screw speeds in certain extrusion concepts, like the High-Speed-S-Truder with a floating screw sleeve, can facilitate gentle conveyance of molten material, preventing the development of a melt pool and ensuring solid-melt separation, which aids in maintaining fiber alignment. Therefore, a balance between screw speed and extrusion concept design is essential to optimize fiber alignment in the extrusion process, considering factors like flow conditions, material properties, and process parameters.Why net evaporation have negative values?

Net evaporation can exhibit negative values due to various factors. Inaccurate observation records and calculations can lead to deviations, including negative evaporation amounts.
